A two-piece saddle for-spinning frames is, of course, not newsin the artnor is itnew 5 to provide fol-longitudinal adjustment of onesaddlemember with reference to the may be shifted to heeen er ll ii lon-fiber we ho wise old 1 l i l he same saddle parts. being ferthree rollsa is the case where sh nrt-fihered staple is beinr; spun. In devices ofthis character, partie- 6 ulurly of the t\\- '-o-pieee tylpe, it isfreonientli, meeessary -to readjust the asaddle from three-roll contactto a tw 0-r0ll. contact and as the operatives are generally of fit classwho ai-e-liahleto make. errors in t-he adjust- -'ii'ie'its, it: is acommon ecenrrenceyfor. the.

SflCld les to be improperly plzicedon some of the rolls of ispinni'ngframe. Further more, in changing one-Saddle member withreference to the other in longitudinal ad 7 justinent, the tensionw-light must'be raised :ii'u l='th e topsedrlle member moved in order toat the lower saddle member; which stradtllest'nwb of the rolls. livhe'refthe sad-1 dles are-inztde in two. parts'the operator is furtherliable to dropthe'lowersacldle mem-' her =ii1uttanntingto raise theupper member ski and make the necessary change for adjustment.

It one (tithe primal objects of the pres 35 (Ht invention to provide-inconjunction with all of the ordinary well. known longitudinal.adjustingfeatures of 2; two-piece saddle, :1-

connecting device between the saddle parts so that one ennnotheinadvertently dropped when .tin-,=other is raised and so that there willlieone'of two positionsto which the lowerszultlle member may be shiftedwhile still attziehi-il to the top siuli'ile member. 11011 the operativewishes to change fii roll, it is only ni' cessary to raise theweightbrought into action. This is all accomplished without anyliability of dropping one or the other of the members of the saddle andinsures proper positioning of the saddle members.

Inthe accompanying drawings, 1, 2 and 3 denote the top rolls and 4, 5,F.- the corresponding drawing rolls of a given set upon a spinningframe. These are suitably mounted in. bearings not specifically shownherein. The rolls 2, 3 represent the back-rolls and 1 the forward rollof a set. Upon the back rolls 2, 3, as illustrated in Fig. 1, rests thesaddle member 7 and this is provided with a bearing surface 8 for theroll 3 and a surface 9 for the roll 2. The upper portion of the saddlemember 7 is channeled as at 10 and into this channel projects a rib 11formed on the under side of the tail of the top saddle member 12. Thissaddle member 12 has a bearing surface 13 for the front roll -1.- Thechannel 10 and rib 11 form a convenient means for preventing lateralseparation of the saddle members and the shoulders 14, 15 at either sideof the rib 11 are formed to extend beyond theside walls'16 of the rib 11and overlie the walls 14, 15, of the channel 10.

The upper saddle member 12 is provided with an adjustable plate 17 whichmay be moved along' t;heupper side of the member 12 and secured in placeby a suitable screw or other clamping device 18. The tension 7 stirrup19 rests upon the forward end of the plate 17 and is held againstlongitudinal movement thereon by the up-turned end'20 and upset lug 21.

Between the top saddle member 12 and lower saddle member 7', there isarranged a '40 Figs; 1 to 5 of the drawings, consists of a hingedconnection which, as illustrated in surfaces 9, 8 will register with therolls 2 and 3, As the lower member is shifted rearwardly, it may beswung until a surface 8 registers with the roll 3 and thereupon the'roll 2 is cleared. It will be seen from this that by raising the uppersaddle member 12 a slight distance the lower mem her 7 maybe swungbackward and forward to a position for engaging both the rolls 2 and 3for spinning a short-fibered sta le or to a position engaging simply thebac roll 3 forspinning long-fibered. staple and that during thisshifting, there is no liability of dropp ng the lower saddle member. InFig.

venient means of forming the necessary I hinged joint between the twoparts of-the saddle and insures freedom from cramping as the parts areassembled, inasmuch as the U-shaped wires may be driven down to the.ends of the small metallic tubes-without cramping against the sides ofthe saddle members.

In Fig. 6, in lieu of using the tubes, a pair of connecting members 27are illustrated, each having a long arm 28 which may project through theperforation of one saddle member and be riveted down-as at29 and withits opposite end in the'form of va short parallel pivot 30. The-use ofthissort of connection necessitates two perforations in each of thesaddle members. i

In Fig. 7, there is illustrated a. form of connecting hinge which issimple and most efficacious and is arran d entirely within the structureof the sadd e-blocks. This consists of a link 31 havingan elongatedperforation 32 at one end and a pivot perforation 33 at the oppositeend. The central portion of the lower saddle member is grooved out asat. 34 from the. top and the lower side of theupper saddle member isgrooved out as at 35 from the bottom. The link 31 is inserted in thegrooves and pins 36, 37 are passed through the respective saddle membersengaging the perforations 32, 33. In this form offlthe device, it willbe noted that the hinged joint is formed interiorly of the structurewhere it is free from liability of becoming foul with lint or dirt andwhere it is not likely to be disarranged.

Of course, it is quite immaterial what extwo saddle parts so long asthey are so hinged together that without transposln act form ofconnection is made between the either of the parts, one may beswung wit1 reference to the other to adjust, as may be desired for two or threerolls or more, as the case may be.

It will be observed that there is no change in all the advantageousfeatures of a saddle block which embodies relative longitudinaladjustment, insurance against transverse displacement and propertensioning. With all these features present, there is the additionaladvantage of being able to shift and adjust the members. relatively toeach other with precision and without liability'of dro ping andnus-placement of. either' of t e mem ers.

In practice, it is preferred to make the saddle members 12 and 7 from atreated fiber which has a homogeneous character'and is self-lubricatingas to its entire structure but, of course, the adjusting feature may beapplied to any desired form of two-piece saddle.

What I claim as my invention and desire to secure by Letters Patent is:

A saddle for spinning frames comprising a top'saddle and bottom saddleadjustably mounted with reference to each other and permanentlyinterconnected by a link member pivoted to each saddle member wherebyone saddle member may be shifted longitudinally into either one of twopositions for adjustment with reference tothe other withoutdisengagement of the parts.

2. A saddle for spinning frames comprising two parts having freelongitudinal movement with reference to. each other and a link pivotallyconnected with both of said parts, though permitting longitudinal'adjustrnent thereof as one is swung with reference to the other, saidconnecting link determining the amount of adjustment between the saddleparts as they are relatively moved into either one of two positions ofadjustment.

3. A saddle for spinning frames comprising two parts havinginterengaging members between the saddle parts permitting longitudinaladjustment thereof, recesses in the meeting engaging portions of bothparts and a pivoted link arranged in said recesses and pivotallyconnected to both of the saddle parts, though. permitting longitudinaladjustment thereof into two definite positions as one is swungrelatively to the other upon the pivoted link.

4. A saddle for spinning frames comprising two parts, one normallyresting upon the other and relatively adjustable into either one of twopositions, recesses in the engaging portions of both parts and a pivotedlink arranged in said recesses and pivotally connected to both of thesaddle parts, though permitting longitudinal adjustment thereof as oneis swung relatively to the other upon the pivoted link.
